Chester Carlson was born in Seattle, Washington.
However, the term On October 22, 1948, ten years to the day after that first Before the Model A, in order to make a paper lithographic master for a lithographic press like the Multigraph 1250, one had two choices: Type up a new master using wax-coated carbon paper on a special master sheet, or use a metal plate coated with a modified silver halide photographic emulsion. Carlson wrote of his mother, Ellen, that she "was looked up to by her sisters as one of the wisest.
"Carlson began thinking about reproducing print early in his life. Due to the inability to work of his father, who suffered from arthritis and tuberculosis, the family lived in bitter poverty.

So I set out to think of how one could be made.Carlson wrote over 400 ideas for new inventions in his personal notebooks while working at Bell Labs. The ions would create an electrostatic charge on the drum. Selényi's article convinced Carlson to instead use light to 'remove' the static charge from a uniformly-ionized On October 22, 1938, they had their historic breakthrough. His pessimism about electrophotography was so strong that he decided to dissolve his agreement with Carlson that would have given Kornei ten percent of Carlson's future proceeds from the invention and partial rights to the inventions they had worked on together.The road to Carlson's success—or that for xerography's success—had been long and filled with failure.
He graduated from Ok State Univ Coll Of Osteo Med medical school in 2006. Three years later the Haloid Company of Rochester, New York, undertook the final conversion of xerography into a commercial product.
Carlson worked his way through college, graduating with a Bachelor of Science degree in physics from California Institute of Technology in 1930.After trying in vain to gain employment as a physicist in California he left for New York City, where the P. R. Mallory Company, an electrical manufacturing firm, offered him a position in its patent department. He quickly became frustrated with traditional duplicating techniques. Both sides were tentative; Battelle was concerned by Haloid's relatively small size, and Haloid had concerns about electrophotography's viability.During this period, Battelle conducted most of the basic research into electrophotography, while Haloid concentrated on trying to make a commercial product out of the results.
Carlson had neither the money, laboratory facilities, nor mechanical talent to transform his experiments into a working copy machine ready for public use. He is best known for inventing electrophotography, the process performed today by millions of photocopiers worldwide. Because the Model A's toner repelled water but attracted oil-based inks, a lithographic master could be made easily by simply making a copy of the document with the Model A onto a blank paper master. It reduced the cost of creating a lithographic master for an existing document from three dollars to less than forty cents.
Exact Date not Known Jan 1, 1930.
Chester Floyd Carlson was an American physicist, inventor, and patent attorney born in Seattle, Washington. At the same time he conducted research on a duplication process that would produce clean copies quickly without using the chemical solutions, film, and printing paper necessary for photographic reproduction.Carlson began his search for an alternative process by reading the available literature on printing, photography, and various copying technologies.
